These drop from the Epic dungeons. They drop as a Rare (Blue) Shard of _____. It takes four Shards of the same type to be combined as any other Enchantment to make a Lesser ____ Enchantment. You can then combine four of the “Lesser’s” into a “Normal”, then four “Normal’s” into a “Greater”. Each of these combines has a 1% chance of success. (So save your AD/ Zen for the Coalescent Ward, this ward guarantees a successful combine).

The Shards have a poor description: “This is an Enchantment shard. Combine 4 of them to create an Enchantment for your Armor or Weapon.”

This does not seem to be the case. Both weapon and Armor enchants have a specific symbol that is shared with the shards. All Armor Enchants have a square outer boarder while all Weapon Enchants have a diamond boarder. Check the boarder of the shard and you can tell which enchant you will create.

The Shards do not give any idea on what their stats will be. So I have listed all of the ones I have found either personally or on the AH.
